Ios WKWebView赢得'；不要打开外部链接

因此，我正在将我的UIWebView应用程序转换为WKWebView，结果发现它无法打开外部网站，如dropbox、facebook等

它在viewDidLoad中加载我的站点，所以这不是问题

例如：

NSURL *nsurl=[NSURL URLWithString:@"example.com"];
NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
[webView loadRequest:nsrequest];

webView.navigationDelegate = self;
webView.UIDelegate = self;
[self.view addSubview:webView];

我打过电话：

-(void)webView:(WKWebView *)webView didStartProvisionalNavigation: (WKNavigation *)navigation {}

- (void)webView:(WKWebView *)webView didFinishNavigation: (WKNavigation *)navigation{}

以及：

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {}

decisionHandler(WKNavigationActionPolicyAllow);

最后，在我的info.plist中，我添加了：

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSExceptionAllowsInsecureHTTPLoads</key>
    <true/>
    <key>NSIncludesSubdomains</key>
    <true/>
    <key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key>
    <true/>
</dict>

NSAppTransportSecurity
NSAllowsArbitraryLoads
N异常低安全Http负载
n包括多个域
N第三方异常低安全Http负载

但什么都不管用。我做错了什么

我们将一如既往地感谢您的任何帮助。

好的，所以我设法得到了它，还有一些被遗忘的网站的帮助（对不起），我设法使它一切正常

下面是我在webview中使用的几乎所有内容

//Webview Start/Finish Request
- (void)webView:(WKWebView *)webView didStartProvisionalNavigation:(WKNavigation *)navigation {
    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
    NSLog(@"didStartProvisionalNavigation: %@", navigation);
}

- (void)webView:(WKWebView *)webView didReceiveServerRedirectForProvisionalNavigation:(WKNavigation *)navigation {
    NSLog(@"didReceiveServerRedirectForProvisionalNavigation: %@", navigation);
}

- (void)webView:(WKWebView *)webView didFailProvisionalNavigation:(WKNavigation *)navigation withError:(NSError *)error {
    NSLog(@"didFailProvisionalNavigation: %@navigation, error: %@", navigation, error);
}

- (void)webView:(WKWebView *)webView didCommitNavigation:(WKNavigation *)navigation {
    NSLog(@"didCommitNavigation: %@", navigation);
}

- (void)webView:(WKWebView *)webView didFinishLoadingNavigation:(WKNavigation *)navigation {
    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
    NSLog(@"didFinishLoadingNavigation: %@", navigation);
}

- (void)webView:(WKWebView *)webView didFailNavigation:(WKNavigation *)navigation withError:(NSError *)error {
    NSLog(@"didFailNavigation: %@, error %@", navigation, error);
}

- (void)_webViewWebProcessDidCrash:(WKWebView *)webView {
    NSLog(@"WebContent process crashed; reloading");
}

- (WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures {

    if (!navigationAction.targetFrame.isMainFrame) {
        [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
        [self.webView loadRequest:navigationAction.request];
    }
    return nil;
}

- (void)webView:(WKWebView *)webView didFinishNavigation: (WKNavigation *)navigation{
    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
    NSLog(@"didFinish: %@; stillLoading:%@", [self.webView URL], (self.webView.loading?@"NO":@"YES"));
}

- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler {
    NSLog(@"decidePolicyForNavigationResponse");
    decisionHandler(WKNavigationResponsePolicyAllow);
}

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {

    if (decisionHandler) {
        decisionHandler(WKNavigationActionPolicyAllow);
    }
}

所以我帮助所有这些帮助某人。

请检查此方法的返回类型

- (WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures {

        if (!navigationAction.targetFrame.isMainFrame) {

            [self.webView loadRequest:navigationAction.request];
        }
        return self.webView;
    }

由于它是WKWebView，如果您返回您的webview，它将为您加载URL并为您提供所需的显示页面。

以下是此答案的swift 3.0版本 添加这两个代表

// webView is WKWebview object  
 webView.navigationDelegate = self;
 webView.uiDelegate = self;

重写这些委托回调方法

  func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = true
        print("didStartProvisionalNavigation: \(navigation)")
    }

func webView(_ webView: WKWebView, didReceiveServerRedirectForProvisionalNavigation navigation: WKNavigation) {
        print("didReceiveServerRedirectForProvisionalNavigation: \(navigation)")
    }

    func webView(_ webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation, withError error: Error) {
        print("didFailProvisionalNavigation: \(navigation), error: \(error)")
    }

func webView(_ webView: WKWebView, didFinishLoading navigation: WKNavigation) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = false
        print("didFinishLoadingNavigation: \(navigation)")
    }


    func _webViewWebProcessDidCrash(_ webView: WKWebView) {
        print("WebContent process crashed; reloading")
    }

func webView(_ webView: WKWebView,createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView?{
        //if <a> tag does not contain attribute or has _blank then navigationAction.targetFrame will return nil
        if let trgFrm = navigationAction.targetFrame {

            if(!trgFrm.isMainFrame){
                UIApplication.shared.isNetworkActivityIndicatorVisible = true
